However, according to the results of correlation assays in which Thsd7a of Eca 109 and EC 9706 cell lines were knocked out using siRNA1 and siRNA2, Thsd7a was capable of promoting cell invasion and migration, indicating the essentiality of Thsd7a to motion capacity in vitro, which agrees with previous non-tumor study of Eichmann A's [17]. This evidence concerns the gene THSD7A and neoplasm.
